1 Claim.

My invention relates to a primer pocket reaming apparatus and moreparticularly to a device having a reamer and a holder therefor, adaptedfor reaming and cleaning a primer pocket of a cartridge case head.

Accordingly an object of my invention is to provide an apparatuscomprising a cartridge holder and a reamer therefor, said holder beingadapted for mounting a cartridge case head therein when ream-ing aprimer pocket within the case head, also, for removing the crimp aroundthe primer, so that said cartridge case may be l e-loaded and be usedagain.

Another. object of my invention is to provide said apparatus with meansfor adjusting the holder of said cartridge case head whereby anystandard size cartridge case may be held in place and when reaming theprimer pocket therein, whether it may be the rim type or a rimless head.

Further object of my invention is to provide said apparatus with aprecision reamer means having a step angle thereon, so that said reamingmay be accomplished in one operation, also, to ream a true prirmerpocket in the cartridge case head, and thereby preventing serious damageto the gun and for preventing the escape of gases when a cartridge isfired therefrom.

My invention also has for its objects to provide such means that arepositive in operation, convenient in use, easily installed in workingposition and easily disconnected therefrom, economical in manufacture,relatively simple, and of general superiority and serviceability.

Other and further objects and advantages of my invention as will hereinafter more fully appear, I attain by the construction herein shown onthe drawings and described in the specification, forming a part of myapplication.

Reference is now had to the accompanying drawings in which the similarreference characters denote the same parts.

In the drawings;

Fig. 1 is a side elevational and partly sectional View of the apparatus,showing a cartridge case holder and a reamer in position.

Fig. 2 is a front elevational view of the apparatus, taken from the leftof Fig. 1.

Fig. -3 is a fragmentary top View thereof.

Fig. 4 is an enlarged fragmentary and partly sectional side view of theholder and showing a reamer when in its reaming position.

Fig. 5 is a fragmentary and sectional view of the holder, taken in thedirection of arrows 5-5 in Fig. 2, and showing the adjustable gage leverin position.

i i i i 2 l 1 Describing my invention more in detail, said inventioncomprises a stand 2, having'a mounting base 4 and a head section 6. l

Said head section 6 is provided with a suitable socketB wherein a reamerI0 is held in a slidable and rotatable position. I l

' The front section l2 of said head 6 is provided with a pair ofadjustable plates I4 and 16, each having a tapered edgelfl adapted forengaging the rim section. 20 of acartridge case head member 22.

Said plates 14 and It are supported upon a pair of washers 24, which arefor the purpose of holding said plates in a'slightly'extended position,

4 thereby facilitating the location of said cartridge case head 22, whenplaced therebetween, as shown I tive positions by means of rivets 28,each being disposed and passing through a suitable slot 30 and eachhaving a screw 32 provided therein for facilitating the adjustments ofsaid plates l4 and I6, as required.

Said front plate 26 including said adjustable plates 14 and I6 are heldin position upon said head 6 by means of a pair of studs 34 and 36, eachof which extends outwardly as shown, and each is provided with apressure spring 38, supported by a washer 40 which bears against thestud head 42, thus allowing the cartridge case head 22 to be held firmlyin place and position.

In order to secure a central position for said partridge case head 22, asuitable adjusting lever or plate 44 is provided, which is mounted uponthe inner side of said front plate 26 and is held in place by means of ascrew 45.

Also, for accommodating variable cartridge head diameters, a suitableside opening 48 is provided in said front plate 26, which is largeenough to permit any size of a cartridge case head to be placed thereinwhen necessary.

For adjusting the extended end 50 of said lever 44 against said casehead 22, in order to hold it in a central position, said front plate 26is provided with a suitable slot 52, so that any suitable adjustment maybe made, and thereby holding said case head 22 in line with said reamersocket 8.

Said reamer I0 at its end, is provided with a primer pocket cutter 54,which is moved inwardly into said socket 8, when said case head 22 isbeing placed into reaming position.

Said reamer II} is also provided with a suit- 3 able extension shank 56upon which a suitable crank member 58 is mounted, having its extendedand 60 provided with a knob 62, so that the turning and rotating of saidreamer l may be facilitated.

When said cartridge case head 22 of the cartridge 64 is set in itsposition, then said reamer I0 is moved frontwardly and into the primepocket 66, and by imposing aslight hand' pressuresaid prime pocket isreamed'correctlyand accurately,"

removing any and all nicks or crimp which may be present and champheringthe edge correctly in one operation.

It may also be noted, that in holding said-case head 22 squarely inposition and against the surface of said front section [2, said 1prime'po'cket- 66 may be reamed true in line, and-thereby an offcenter,oblong or sideward reaming of the pocket is prevented.

While I have thus described my invention with great particularity, itwill-be clear that the-same maybemodified throughout a wide range.

I accordingly do notpropos'e tobelimitedto the: exact details-ofconstruction herein shown and described, but reserve the rights inpractice to make the necessary changes and modifications therein whichmayc'ome within'the scope of the appended'claim'.

I claim as my invention;

In-a device of the class described'comprising, a stand having a base anda head member, a reamer rotatablymounted in said head member havingthe-:frontend thereof terminating with a primer pocket cutter, acrankmember attherearwardly extending end of said reamer, a front surface insaid head member, a pair of studs mounted in and extending frontwardlyfrom said front surface, a washer on each stud, a front plate mounted onsaid studs, a pair of adjustable front plates mounted between said frontplate and said washers, a tapered edge in each front plate for engagingthe rim section of a cartridge case, an adjustable lever platemountediupomsaid front plate havi'ngthe extended endthereof disposed'inclose proximity to said pair of adjustable front plates for holding thehead of said cartridge case in a central position'and at the center linewith said rotatable reamer, and a pair of resilient means at themounting of said front plate means for forcing the head of saidcartridge case squarely against the front-surface of said head memberand for holding said cartridge case head rigidly in position when saidprimer pocket is being reamed.
